NTSB narrative
The World War II vintage airplane's engine experienced a total loss of power shortly after takeoff. During the forced landing, the airplane collided with electrical power lines and the ground. The pilot said the airplane's engine had been experiencing vapor lock problems in the past and that the engine had quit in the same manner as before. The airplane's fuel tank had leaked about 25-gallons of fuel on the ground after the accident had occurred. According to the pilot, the airplane's side cowling assemblies were taken off when the outside air temperature (OAT) exceeded 45-degrees Fahrenheit. This was supposed to eliminate the vapor lock potential. The OAT on the day of the accident was 80- degrees Fahrenheit. The airplane's side cowling had been removed before the accident flight. No other mechanical anomalies were found that would identify why the engine experienced a total loss of power.
Probable cause
the pilot selected to operate the airplane with a known deficiency. A factor in this accident was the vapor lock experienced by the engine's carburetor.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
